Portable tankless water heaters....
Could I use one of these to fill a mini bathtub on my patio? I would just like to soak every so often. Many of them produce 2 gallons of hot water a minute...the question is how hot. Anyone know?

Put a black barrel or bladder in the air, high enough for gravity flow. Put it in the sun and report back the water temperatures. I guarantee it will be too hot, in most cases, if left to achieve maximum temp. The differential then becomes time left in the sun rather than temp rise/flow of a gas unit.
